A branch of a merchant house, a river and a dragon.

Kokuryu is the sake of Kokuryu Shuzo, a brewery in Matsuoka in the town of Eiheiji, Fukui Prefecture, on the Sea of Japan side of central Honshu. The company says it was founded in 1804, the first year of the Bunka era, when Ishidaya Nizaemon branched off from the main Ishidaya house and began brewing on the site in Matsuoka Kasuga where the head office still stands. Japanese Wikipedia gives the same founding story.

The family and the business have changed names more than once. According to the company’s own timeline, the brewery was trading as Mizuno Shuzo-ba by 1894, and the Mizuno family still runs it. Records from that period already mention a brand called Kokuryu — “black dragon” — taken from Kokuryu-gawa, an old name for the Kuzuryu River that runs past the town. The company gives April 1948 as the date of its incorporation and 1963 as the year it took the name Kokuryu Shuzo.

The river is part of the brewery’s account of itself in more than name. In an interview published by the web magazine OPENERS in November 2017, the eighth-generation head, Naoto Mizuno, described the brewing water as underground water from the Kuzuryu, part of the Hakusan water system. The company lists him as its representative and says he became president in 2005.

The town takes its name from the Zen temple Eihei-ji, and the brewery has its own place in it. Japanese Wikipedia records that three of the brewery’s buildings were entered on Japan’s register of tangible cultural properties in 2011. The brewery has added new buildings alongside the old ones: the company dates its Ryushokura brewery to 1994 and its Seiryuzo brewery to 2017, and Naoto Mizuno told OPENERS that Seiryuzo takes one character from the name of his father and predecessor, Masato Mizuno.

Cold sake, an early daiginjo and labels that look like old cloth.

Daiginjo, the most highly polished grade of sake, and the idea of serving it cold run through Kokuryu’s history. The company’s timeline says it launched COLD KOKURYU in 1970 to propose drinking sake chilled, and released Kokuryu Daiginjo Ryu and Kokuryu Icchorai in 1975. OPENERS introduced the brewery in 2017 as a pioneer in producing and selling daiginjo, and Naoto Mizuno told the magazine that the early sales effort amounted to little more than asking customers to put the bottle in the refrigerator.

The labels changed with the rules. Japan’s old grading system for sake was abolished in 1992, and the company says that in that year it redesigned its labels to evoke old cloth, with traditional Japanese beauty in mind. The bottle followed: the company says it introduced an original 720 ml bottle in 2008, the same year it fitted a clean room to its bottling line.

Maturation is the other thread. In 2005 the company built its Kanesadashima site, which it calls a village for sake-making, to give its undiluted sake thorough low-temperature ageing, and added a product warehouse there in 2012. The company’s current chief brewer, Hiroshi Hatayama, joined in 1995, the year the company says it began training its own employees as brewers.

Kokuryu has also been sent abroad for some time. Naoto Mizuno told OPENERS in 2017 that the brewery had been exporting for nearly 20 years, though exports remained a small share of its output, and that overseas drinkers were surprised that so elegant and delicate a sake existed.

Design and documentation.

The seven brands in this group are all Japanese sake breweries: Juyondai, Kokuryu, Dewazakura, Tatenokawa, Hakutsuru, Kizakura and Masumi. Sake breweries in general sit at many different points in the trade, from small family kura that still carry a founding family’s name to larger companies with brands sold far beyond their home region, and a single sake can be found everywhere from a local shop to a restaurant list abroad.

A sake brand’s identity is usually carried less by a single bottle than by a label, a name and the place it promises, because the company behind the name may have changed hands, added new breweries or grown far beyond the town where it started. That makes the questions behind each name worth asking plainly: who started it, who owns it now, and where its sake is actually brewed and bottled.

Each guide separates what independent sources record from what the company says about itself — its founding story, its owners over time, where its sake is brewed and how its labels have changed — and marks plainly what rests only on the company’s own word.

Two dragons, an auction and a riverside complex.

The brewery now runs two main brands that share the river’s name. The company says it launched Kuzuryu as a sister product in 1959, and in 2004, its 200th year, it released a Kuzuryu daiginjo meant for warming, together with a sake warmer called Kan Tanoshi. Japanese Wikipedia reports that in April 2021 the lineup was reorganised so that Kokuryu became the brand for gifts and special occasions and Kuzuryu the brand for drinking at home. A third name sits above both: the company says it launched Muni in 2018 and held what it describes as the sake industry’s first auction for it.

Kokuryu turned to other work in 2020. The company says it released a sake to support restaurants and produced and supplied alcohol for disinfection during the pandemic.

The latest chapter sits outside the brewery. In 2022 the family opened ESHIKOTO, a complex beside the Kuzuryu River in the Shimojohoji district of Eiheiji, operated by a separate company named Ishidaya Nizaemon after the founder. ESHIKOTO’s own site calls it both a sake brand and a place that uses sake to convey the culture of Fukui and the Hokuriku region; it houses the Ishidaya ESHIKOTO sake shop, a restaurant and pâtisserie called acoya, a soba restaurant, a bakery and an auberge of eight villas. The regional tourism site Shoryudo explains the name as Fukui dialect: “eshi” means “good” or “great,” and “koto” means “thing.”

Online, the brewery’s site is kokuryu.co.jp, while ESHIKOTO keeps its own at eshikoto.com, and the river name Kuzuryu is spelled with different characters from the black-dragon brand Kokuryu.

For a design guide, Kokuryu shows how a river’s old name, a black-dragon wordmark and labels made to look like old cloth can carry a family brewery from the Edo period to a daiginjo house with its own riverside destination. Compare Hakkaisan, the Niigata sake named after a mountain, and Gekkeikan, the Fushimi house of 1637. For this guide we use dragon black, river indigo and old-cloth beige with a Mincho serif, an unofficial interpretation; no product or logo is reproduced.
